Error:

Hello there,

The error message tends to suggest you can;t connect to EOL. That could be because of a bad password.

One trick that sometimes works - use the -Verbose switch - it can give you more details as to what went wrong.

Any chance a corporate security product is blocking it, say something like zscaler for traffic filtering on the network level, or local AV product?

The below thread discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue.

Try to connect to Exchange Online with the command below: Connect-ExchangeOnline -UserPrincipalName ******@domain.onmicrosoft.com If there exists an issue with it, I would suggest you use the command below to uninstall Exchange online module and reinstall it (Run those command in an elevated PowerShell window): Uninstall-Module -Name ExchangeOnlineManagement Install-Module -Name ExchangeOnlineManagement   For EXO V2 module 2.0.5, you also need to check the setting below: ExecutionPolicy set as "RemoteSigned": Set-ExecutionPolicy RemoteSigned Basic is enabled on the client: winrm get winrm/config/client/auth For more detailed information, check this article - have a look about this article.
